Definitions

  • the present invention relates to a supporting structure of the type pointed out in the preamble of the first claim.
  • the invention relates to a structure adapted to form a raised support for a scaffold or wooden board and therefore to enable a work surface to be defined, referred to as walking deck, on which an operator can walk, work, lay down tools while working.
  • This structure therefore can be used for making scaffolds to be employed for building or painting works in order to define a comfortable and practical walking deck, i.e. an appropriate work surface.
  • scaffolds are usually defined by a plurality of frames for scaffolding substantially having an H-shaped configuration and joined together by suitable section members.
  • said H-shaped configuration of the frame for scaffolding is defined by two vertical elements, usually referred to as posts, a horizontal element called beam, adapted to mutually fasten the two posts and to enable positioning of a scaffold or wooden board.
  • a horizontal element called beam adapted to mutually fasten the two posts and to enable positioning of a scaffold or wooden board.
  • it can have two reinforcing elements disposed obliquely and fastened to the beam and to one post.
  • Said frames are generally positioned close to vertical walls to be treated, external building walls or façades for example.
  • the frames are placed at a distance from the wall and not directly in contact therewith so as to enable works to be carried out with a single structure on the whole wall having unevennesses and portions projecting from the wall itself.
  • a distance is also established by regulations and in Italy for instance article 138 paragraph 2 of the Legislative Decree 3 August 2009, No. 106 determines a distance between the boards of the walking deck, i.e. the scaffold boards, and the masonry walls not exceeding 20 centimetres. Actually, a greater distance would create an empty space or gap between structure and wall that is particularly dangerous. In fact, through this gap bricks and buckets or other objects could fall down from the walking deck and they could hit and consequently injure a person that is under said deck.
  • said empty space can be of such an extension that an operator who is on the deck could pass therethrough and therefore fall down.
  • a greater distance has to be necessarily provided between the frames and the wall, for instance in order to enable a single structure to be used for working on a wall including windowsills, terraces or other elements jutting out of the outer wall of a building.
  • the frames of the supporting structure can be provided with suitable safety apparatus to be mounted on and fastened to the frames themselves.
  • these safety apparatus have a first tubular element adapted to the secured to the frame in such a manner that it is disposed parallel to the beam and defines a support point on which a scaffold board is disposed so as to create a provisional walking deck included between the frames and the wall.
  • said apparatus has fastening means such as joints or friction fits enabling the apparatus to be locked at a beam or a post.
  • the technical task underlying the present invention is to conceive a supporting structure capable of substantially obviating the mentioned drawbacks.
  • the supporting structure 1 can be used for manufacture of a scaffolding system, i.e. a reticular assembly such as a scaffold 10 to be used for works in the building field such as construction, painting and maintenance of buildings.
  • a scaffolding system i.e. a reticular assembly such as a scaffold 10 to be used for works in the building field such as construction, painting and maintenance of buildings.
  • scaffold 10 obtained through use of a plurality of supporting structures 1.
  • scaffold 10 has two supporting structures 1, two section members 11 adapted to secure the two structures 1 to each other, and two scaffold boards 12 each of which defines a walking deck, as better pointed out in the following.
  • the supporting structure 1 comprises a frame for scaffolding 2 adapted to support a scaffold board 12 defining a first walking deck 1a and a support body 3 secured to the frame for scaffolding 2 in a motion-admitting manner, in particular made of wood in the first length and metal in the second length.
  • frame for scaffolding identifies any apparatus usable in the building field for manufacture of a scaffolding and therefore adapted to enable at least one steady walking deck to be defined which is placed in a raised position relative to the ground so as to enable the operator to work comfortably on the whole extension of a building wall.
  • the frame for scaffolding 2 comprises a plurality of section members among which it is possible to identify at least one beam 2a adapted to support the first walking deck 1 a in the correct position and at least one post 2b adapted to support said first walking deck 1 a in a raised position relative to the ground.
  • the frame for scaffolding 2 has only one beam 2a defining a first preferred extension direction substantially parallel to the walking deck and two posts 2b suitably secured close to the ends of beam 2a so as to enclose said beam and therefore the first walking desk 1 a.
  • the frame for scaffolding 2 may comprise reinforcing elements 2c, i.e. suitably shaped section members secured to beam 2a and post 2b so as to give the frame itself greater steadiness.
  • the supporting structure 1 further comprises the support body 3 secured in a motion-admitting manner to the frame for scaffolding 2, which body preferably consists of a section member having a second preferred extension direction and susceptible of movement relative to the frame for scaffolding 2 so that it can be disposed either in a closed position or in at least one use position.
  • the support body 3 is almost adjacent to frame 2 and positioned in such a manner that the supporting structure 1 substantially has the same overall dimensions as the frame for scaffolding 2, i.e. in such a manner as to give rise to a difference between the overall sizes of the supporting structure 1 and those of the frame for scaffolding 2 of less than 15% and more exactly less than 10%.
  • the support body 3 is positioned substantially in overhang relative to the frame for scaffolding 2 in such a manner as to give rise to an advantageous increase in the overall dimensions of the supporting structure 1.
  • the support body 3 extends to the outside of the frame for scaffolding 2, i.e. on the opposite side relative to that enclosed by the two posts, and defines a support external to the frame and adapted to bear a further scaffold board 12 and therefore an additional walking deck 1b external to the first walking deck 1 a.
  • the support body 3 has the second preferred extension direction substantially coincident with the preferred extension direction of the beam 2a.
  • the supporting structure 1 has a seat 4 ( Fig. 5 ) adapted to substantially house the whole of the support body 3 when the latter is in said closed position.
  • the support body 3 in the closed position has a portion external to seat 4 having an extension of less than 10 cm so as to facilitate gripping and therefore movement of the body itself. In some cases, it can in addition have the end of this external portion such shaped as to facilitate gripping and therefore movement of body 3.
  • Seat 4 therefore substantially consists of a housing adapted to receive this support body 3 and having a third preferred extension direction 4a substantially rectilinear, relative to which direction said body 3 is moved.
  • the third preferred extension direction 4a is substantially parallel to the first preferred extension direction of beam 2a and, more preferably, these preferred extension directions are almost coincident with each other so that the support body 3 is substantially housed within the frame for scaffolding 2 and, more specifically, within beam 2a when said body 3 is in said closed position.
  • seat 4 is substantially made up of a cavity formed in beam 2a and inside which the support body 3 is at least partly housed so that the three preferred directions of the support body 3, beam 2 and seat 4 are substantially coincident.
  • the support body 3 has a section of slightly smaller sizes than the size of beam 2a so as to obtain an accurate movement of the body itself.
  • the supporting structure 1 finally comprises a prop assembly 5 adapted to bear the support body 3 when the latter is in its use position and therefore is substantially in overhang relative to the frame for scaffolding 2.
  • the prop assembly 5 is fastened in a motion-admitting manner to one post 2b and to said outer portion of the support body 3 so as to ensure a relative motion thereof with respect both to body 3 and frame 2.
  • the prop assembly 5 is pivotally mounted on post 2b and body 3 so that it can freely rotate relative to the post 2b and the support body 3 when said body 3 varies its position.
  • the prop assembly 5 is made up of a telescopic component, i.e. a component adapted to vary its length, and therefore comprises an inner section member 5a and an outer section member 5b having a cavity adapted to house the inner section member 5a and to enable mutual motion between said section members 5a and 5b when the support body 3 varies its position.
  • a telescopic component i.e. a component adapted to vary its length
  • the prop assembly 5 when the support body 3 is in the closed position, the prop assembly 5 has minimum sizes and therefore the inner section member 5a is almost entirely housed inside the outer section member 5b ( Fig. 2a ).
  • the prop assembly 5 when the support body 3 is in one of its use positions, the prop assembly 5 has greater sizes than in the previous case and therefore the inner section member 5a has at least partly come out of the outer section member 5b ( Figs. 2b-2c ).
  • structure 1 comprises locking means 6 housed within the prop assembly 5 and adapted to fixedly fasten the inner section member 5a to the outer section member 5b so as to lock the support body 3 to a given position relative to seat 4, thereby defining a use position.
  • Said locking means is preferably rigidly connected to the inner section member 5a and has a spring 6a and a slider 6b that, being pushed by the spring, is adapted to enter suitable holes 6c formed in the outer section member 5b thereby mutually securing the two section members 5a and 5b ( Fig. 4 ).
  • positioning of holes 6c is envisaged in such a manner that, as hereinafter described, the locking means 6 defines a first use position in which the support body 3 comes out of the seat over a length of at least 250 mm, as shown in Fig. 2b , and a second use position in which the support body 3 comes out of the seat over a length of at least 500 mm, as shown in Fig. 2c .
  • a scaffold 10 is prepared in the vicinity of the wall of a building to be renovated.
  • preparation is carried out, in known manner, by fastening a plurality of supporting or base structures 1 to each other and placing a plurality of scaffold boards 12 on the beams, each board defining a first walking deck 1 a.
  • the operator moves the two support bodies 3, belonging to the two base structures 1 supporting board 12, close to the façade portion to be worked, causing them to switch from the closed position to the most suitable use position for the work situation.
  • the operator places the support body 3 in the first use configuration, while if this distance is greater than 500 mm, the support body 3 is arranged to the second use configuration.
  • movement of the support body 3 causes the prop assembly 5 to rotate and simultaneously the inner section member 5a to partly come out of the outer section member 5b until spring 6a belonging to the locking means pushes slider 6b into one of holes 6c formed in the outer section member 5b, thus fastening the inner section member 5a to the outer section member 5b and therefore locking the prop assembly 5 and support body 2 to such a position.
  • the operator places a scaffold board 12 thereon thus forming an additional walking deck 1 b which is at a distance from the wall in compliance with the safety rules in force.
  • the invention achieves important advantages.
  • the supporting structure 1 allows scaffolds 10 to be made that are in compliance with the safety rules in force.
  • the supporting structure 1 is able to define an additional walking deck 1b sufficiently close to the wall, irrespective of the presence of elements such as balconies and consoles emerging from the wall over lengths different from each other.
  • Another advantage of the supporting structure 1 is represented by the integration of the support body 3 with frame 2 and, in particular, by the fact that body 3 is housed in beam 2a.
  • this particular placement allows a closed position to be defined in which the supporting structure 1 substantially has the same overall dimensions as known frames for scaffolding so that no particular warehouses for storage are required and transport of same is simple and practical, in spite of the presence of the support body 3 secured to the frame.
  • a further advantage resulting from the particular placement of the support body 3 is given by the great simplicity and high speed of mounting of the additional walking deck 1b. This aspect is further ensured by the complete absence of screws, joints, bolts or other fastening means requiring complicated operation.
  • a further advantage also of importance is represented by the almost same height between the walking deck 1 a and the additional one 1 b, as also shown in Figs. 2b and 2c and, as a result, by the absence of dangerous differences of level between the two walking decks 1a and 1b.
  • This advantage is obtained due to the substantial coincidence between the preferred extension direction of the support body 3 and that of beam 2 and also to the reduced difference between the two sections enabling two supports for scaffold boards 12 and, as a result, two walking decks 1 a and 1 b substantially at the same height to be defined.
